Abstract

To rapidly and accurately detect the geometric precision of numerical control(NC)machine tool

a method based on the multi-station and time-sharing measurement principle was proposed. A laser tracker was used to measure the same 3D motion trajectory of the machine tool moving components at different base stations

and the over-determined equations were established based on large amount of measured data concerning the distance variation between measuring point and base point. The coordinates of each measuring point during motion can be accurately calibrated by solving the equations with least squares method

then the geometric errors of the machine can be separated. The principles of multi-station and time-sharing measurement were analyzed

and the algorithms of multi-station and time-sharing measurement were given

and the measurement errors of the method were discussed. The simulation and experiments verify the feasibility and accuracy of this multi-station and time-sharing measurement method

which is suitable for medium-high level of NC machine in geometric precision detection.
